Specification forming part of Letters Patent No. 102,993, dated May 10, 1870.

To all 'whom it may concern:`

Be it 'known that I, NATHAN G. WEBBER,

of East Springfield, in the county ot' Erie and Fig. 2 represents a side elevation, showing the handles ofthe cultivator turned up and iolded' over and upon the beam. Fig. 3 represents a planof the same.

VMy invention consists in constructing the beam ofthe cultivator withv a metallic fixed bow, upon which the shovels are secured in ,p such manner that they may be adjusted nearer to or farther from eachother in a curved line,

`, and secured by wedges, in whatever position they may be adjusted, without the necessity of mounting them upon hinged frames or arms,

whereby obtain a more durable and cheaper cultivator than Aheretofore constructed; also,

in hinging.V and supporting the handlestipon thebeam in such manner thatthey may bc folded up over the beam when not required for use, or when being shipped or stored away,

thus rendering the cultivator more compact for the purposes stated.

In the accompanying drawings, A represents the beam,to the front and rearv ends ofWhich the plow-teeth B C are secured in any suitable manner, and of any suitable construction.

To the front end of the beam a roller, D, is attached, for preventing thel front furrow plow from penetrating too deeply, and in the rear thereof two semicircular plates, E, are secured, having a series of holes, into any one ofwhich the clevis F'is adjusted for r'egulatingthe depth of the cnltivator shovels.

'Near the middle of the length of the beam I secure a metallic bow,G,the sides of which e are curved outward and are fixed, and upon the curved sidesv of which the cultivator-shovels K are arranged, and secured by meansof `iron Shanks H, having loops in their upper ends, which embrace the curved sides of the fixed bow Gr, so that they may be moved toward and from each other and the beam, according to the width ofthe rows of plants being cultivated, and secured tirmly by' Wedges a inserted into theloop in the shanks H, above or beneath and against the, curved arms'ofthe bow G, so as to hold them when adjusted.'

This arrangement ot' the fixed bow enablesme to adjust the shovels directly, instead of the frame which carries them, and is therefore more convenient and durable as a Ixed instead of ahinged frame. B v this arrangement the angles which the shovels maintain' to each Aother Vand to the bcain can be more easily adjusted and held ini position.

The shovels are made removable, so that they can be replaced by othersotl different' shape and size, when desirable, Withoutremoving their shanks from :the fixed bow.V

The handles I are hinged to the beam at b, within the bow-frame, and supported by aconnecting yoke-shaped brace,J, which rests upon the beam when the'cultivator is 1n use, as shown in` Fig. 3, so that it may be managed with as much rmness as if the handles were l bolted to the beam in the usual manner, while hinging and supporting them in this manner d allow them to be folded up over the beam, as

shown in Figs. l and 2, renderingthe cultiva-4 tor more compact for transportation and storage, which is a very great advantage over the Along xed projecting handles.

lt' it should be deemed necessary to make the` connection of' the handles with the beam xed while managing and lifting the cultivator to turn it, a bolt, c, is secured to the top of the beam, so as to enter an opening in the I Asupporting end of the bracing-yoke J, arid thus lock the handles to the beam.'

Having thus described my claim- The arrangement of the ftxedbow G, the adjustable shovels K, the hinged folding handles invention, I

l, and thelocking and bracing yoke J, as herein shown and described,` and for the purpose specied. NATHAN G. WEBBER.; l Witnesses: f I. `NEWTON MILLER,
